Abstract
Optical interconnects for IC chips may include optical sources and receivers integrated with the IC chips. MicroLEDs may be mounted on an interconnect layer of the IC chip, and embedded within a waveguide. Photodetectors to receive light from the waveguide may be fabricated in a top surface of a semiconductor substrate, below a level of the interconnect layer, but with a passageway for light through the interconnect layer.
